From: Geert Uytterhoeven Date: Mon, 29 Jun 2020 12:11:46 +0000 (+0200) Subject: iommu: SUN50I_IOMMU should depend on HAS_DMA X-Git-Tag: v5.8-rc6~37^2~3 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c7451e495b2abfc35b2bb4347c8d0aaa7699df26;p=thirdparty%2Fkernel%2Flinux.git iommu: SUN50I_IOMMU should depend on HAS_DMA If NO_DMA=y (e.g. Sun-3 all{mod,yes}-config): drivers/iommu/dma-iommu.o: In function `iommu_dma_mmap': dma-iommu.c:(.text+0x92e): undefined reference to `dma_pgprot' IOMMU_DMA must not be selected, unless HAS_DMA=y. Hence fix this by making SUN50I_IOMMU depend on HAS_DMA.
